variable_scope_angularjs.js

//Lets assume value.questionUniqueId is coming from json response
var dataModel = $parse('data_' + value.questionUniqueId);
var dataModel1 = $parse(value.questionUniqueId + '_data');
var labelsModel = $parse('labels_' + value.questionUniqueId);
var seriesModel = $parse('series_' + value.questionUniqueId);
dataModel.assign($scope, ['1', '2', '3', '4', '5']);
dataModel1.assign($scope, ['1', '2', '3', '4', '5']);
labelsModel.assign($scope, [
          [3, 0, 1, 4, 6]
    ]);
seriesModel.assign($scope, ['Series A']);
